Overview of miRNA repression
miRNA are short (22-24 nt) strands of RNA known to regulate gene expression through repression of mRNA. mRNA that contain the complementary sequence to the miRNA are targeted by the RNA-induced silencing complex and are selectively degraded, thus repressing protein production.
Our goal is to use miRNA as a signal for cell-cell communication. We believe this can be accomplished by the packaging of miRNA into exosomes, which would then carry the miRNA signal to a receiver cell. Further, certain miRNA seem to be selectively targeted to exosomes, through a mechanism which is poorly understood. It has been shown that in Jurkat T cells, exosomes are naturally enriched in miR-451 and miR-503. For this reason, we chose to use Jurkat cells as our sender cells and to design a receiver circuit which could detect these two miRNA.
